A device’s vStorage API for Array Integration (VAAI) support status command line output shows:
naa.500253825002a865 VAAI Plugin Name: ATS Status: unsupported Clone Status: unsupported Zero Status: supported Delete Status: unsupported
What is the corresponding VAAI support status in the vSphere Web Client?
A. Unknown
B. Supported
C. Not supported
D. Unsupported
Correct Answer: A
Explanation/Reference:
Explanation : If you go to Host > Configuration > Storage, you can see the Hardware Acceleration Status in the panel on the right side.
For each storage device and datastore, the vSphere Client displays the hardware acceleration support status in the Hardware Acceleration column of the Devices view and the Datastores view.
The status values are Unknown, Supported, and Not Supported. The initial value is Unknown. The status changes to Supportedafter the host successfully performs the offload basic operations. If the offload operation fails, the status changes to Not Supported.
To determine if your storage device supports VAAI, test the Full Copy VAAI primitive:
1.Using the vSphere Client, browse the datastore and locate a virtual disk (VMDK) of at least 4 MB that is not in use.
2.Copy the virtual disk to a new file.
3.Check the Hardware Acceleration status to verify that it changes from Unknown to either Supported or Not Supported.
Note: VAAI primitives can also be tested by creating a virtual machine with at least one new virtual disk, or cloning a virtual machine.
Can I check the VAAI status from the command line?
On ESXi 5.x
To check the VAAI status, run this command:
# esxcli storage core device vaai status get You see output similar to:
mpx.vmhba1:C0:T1:L0 VAAI Plugin Name:
ATS Status: unsupported
Clone Status: unsupported Zero Status: unsupported Delete Status: unsupported mpx.vmhba1:C0:T0:L0 VAAI Plugin Name:
ATS Status: unsupported
Clone Status: unsupported Zero Status: unsupported
Delete Status: unsupported
